The Chevrolet Volt has been battered and bruised over the course of the past six months. The vehicle has weathered an NHTSA investigation into fires, attacks from the members of the media, and production slowdowns. However, General Motors is now touting that the plug-in hybrid had its best sales ever during the month of March.

According to Bloomberg, over 2,000 Volts were sold during the month, surpassing the previous high of 1,529 units in December 2011. GM also claims that it sold over 100,000 vehicles during the month that have an EPA rating of 30 mpg or better. Rather conveniently, GM only cites the highway rating instead of the combined rating to reach that 100,000 figure -- the EPA combined rating takes into account both city and highway fuel economy and is closer to what most drivers will see in the real world.

"GM's strategic investments in four-cylinder and turbocharged engines, advanced transmissions and vehicle electrification have been very well timed," said Mark Reuss, president of GM North America. "Three years ago, about 16 percent of the vehicles GM sold achieved at least 30 mpg on the highway. Today, that number is about 40 percent, and we have more new fuel-economy leaders on the way."
